Product Details

The arrester is mainly composed of zinc oxide varistor valve sleeve, compression spring, threaded sleeve, silicone rubber housing and other parts. Contact pressure zinc oxide varistor valve is guaranteed by the compression spring, completed by the upper and lower fixed threaded sleeve. Zinc oxide arrester is the core of the resistance valve is fired by a variety of chemical materials made of high-resistance performance characteristics are presented at the rated voltage, when the voltage generated in the system line exceeds the rated voltage of the zinc oxide valve resistance automatically converted into a low-resistance state, by means of the cable into the earth, so as to achieve the purpose of protection of electrical equipment.
